Yes, I certainly would turn it over, after having made copies myself of the contents of the camera's memory. Perhaps photos Natalee deleted could be recovered by investigators and lead to new clues. There is just no reason to keep it from them.
One a certain level I appreciate the point you are making. The Arubans have consistently bad-mouthed NH, calling her a slut and a drunk.
Even if there were something on the phone and/or camera Beth wished to conceal, the fact of the matter is that even if the ugly picture the locals painted is true, it's no excuse for her losing her life over it. I've even read remarks that 'she got what she deserved' and that flat out makes me want to puke!
There's no excuse for that and it certainly has left me with a permanently bad opinion of the place. I'm sure there are many people who don't stand on priniciple like that, and they will save the savage island. I am NOT with them.
